Wish I could but like most of the volunteers here I have significant time constraints. Since we're not paid but are volunteers, the brunt of effort here needs to be on the person asking the question, and in that light, your best bet is to read the Sun/Oracle tutorials on how to use Swing Timers and table renderers and then try it yourself in a small demo program to test the concept. If this doesn't work, then post this small test program here and we can help you.
